Will The Vaccine Prevent Covid

Can I Get The Covid

Dr. Fauci: COVID vaccine will help prevent more mutations

In the U.S., the CDC recommends waiting until COVID-19 symptoms go away and the individual is done;isolating. However, they indicate that it is okay to get the COVID-19 vaccine shortly after recovering from the disease as long as the patient was not treated with antibody-based treatments .

Due to limited supplies of vaccine in some countries and the experience that people who recently had COVID-19 rarely get re-infected in the months immediately after recovery, some areas may be delaying vaccination of recently recovered individuals. As such, we recommend talking with your healthcare provider or health officials to see what the recommendations are in your area.

What Should I Do If I Had The J&j Vaccine

If you had the J&J vaccine more than 3 weeks ago, you are extremely unlikely;to experience either thrombosis with thrombocytopenia syndrome or Guillain-Barré syndrome .

If you had the J&J vaccine within the last 3 weeks, although the risk is low, you should still monitor yourself for unusual symptoms, including severe headache, severe abdominal pain, unexplained leg pain, or shortness of breath, which may result from TTS, or muscle weakness or paralysis, which may result from GBS. If you develop unusual symptoms, you should seek medical attention and be certain to tell the healthcare provider the date you received the J&J vaccine. For TTS, the physician can very quickly determine whether your problem is related to the vaccine by performing a simple complete blood count. If the platelet count is extremely low, the symptoms might be related to the vaccine. We would also recommend registering for v-safe, the CDCs vaccine monitoring system if you have not done so already.

Is It Safe For My Adolescent Or Teen To Get The Covid

The Pfizer COVID-19 mRNA vaccine is approved for those 12 years of age and older. Other COVID-19 vaccines are still being tested in those younger than 18 years of age.When the Pfizer vaccine was tested in 12- to 18-year-olds, it was found to be safe:

Do I Need The Vaccine If I Have Already Had Covid

Even if you had COVID-19, the CDC still recommends getting vaccinated. Thats because experts do not yet know how long you are protected from getting sick again after recovering from COVID-19. Even if you have already recovered from COVID-19, it is possible although rare that you could be infected with the virus that causes COVID-19 again, the agency explains.

Have questions? Talk to your doctor.

Essentially, what a vaccine is doing is teaching the immune system how to handle something before you actually encounter the real thing so that, hopefully, when you do encounter the real thing, youre able to deal with it quickly and get rid of it.

I Have Been Hearing About Heart Problems In Kids And Young Adults Following The Covid Vaccine Should I Still Get My Child Vaccinated

Palestinians accuse Israel of preventing COVID

There has a been a higher-than-expected number of heart inflammation cases after vaccination with the mRNA COVID-19 vaccines, particularly among boys and young men. However, the CDC still strongly recommends that all children 12 years and older be vaccinated.

As of July 12, 2021, 1,047 reports of myocarditis and pericarditis had been reported in people under age 30, particularly in male teens and young adults, after vaccination with the Pfizer/BioNTech or Moderna mRNA vaccines The CDCs Advisory Committee on Immunization Practices has said available data “suggest likely association of myocarditis with mRNA vaccination in adolescents and young adults.” Even with the increased risk, heart inflammation is a rare occurrence.

Myocarditis and pericarditis after vaccination was most common in males ages 16 to 24. Cases tended to occur within several days after the second mRNA vaccine dose. Most people who developed myocarditis or pericarditis had mild cases and recovered completely after treatment.

If your child develops any of the following symptoms within a week of vaccination, seek medical care:

  • chest pain
  • shortness of breath
  • feeling like your heart is beating fast, fluttering, or pounding.

Don’t Miss: How Long Will Immunity To Covid-19 Last

Can I Take Medicine For The Side Effects After I Get The Vaccine

The CDC has indicated that you can take anti-fever or anti-inflammatory medications if necessary following COVID-19 vaccination, but it is important to know that doing so could diminish the level of immunity that develops. This is true anytime you take these types of medications, whether following vaccination or to treat illness. Generally speaking, the symptoms people experience following vaccination or during illness, such as fever, redness, or fatigue, are caused by your immune system responding. For example, fever is your body turning up its thermostat to make the immune system more efficient and the pathogen less efficient. For these reasons, if you are not very uncomfortable, it is better not to take these medications.

Some wonder how long they should wait after vaccination before taking these types of medicines, so their immune response is not affected. As a rule of thumb, the immune response for the mRNA vaccines develop over a week or two after vaccination and for the adenovirus vaccines over the course of about four weeks, but the greatest chance of affecting your immune response would be in the first few days after receipt of the vaccine. Indeed, in the adenovirus vaccine studies, about 1 in 4 vaccine recipients took fever-reducing medication , and most people were still protected from severe disease and all were protected against hospitalization.

What Does Fully Vaccinated Mean

According to CDC guidelines, you are fully vaccinated when it has been:

  • Two weeks after your second dose in a two-dose series, such as the Pfizer or Moderna vaccines.
  • Two weeks after a single dose of the Johnson & Johnson vaccine.;However, data from clinical trials are clear that there is further improvement four weeks after the single-shot vaccine, especially for preventing severe COVID-19 or having asymptomatic infection. For this reason, Johns Hopkins Medicine recommends four weeks after the single-dose vaccine to be considered fully vaccinated.

If you dont meet these requirements, you are not fully vaccinated.

If I Get A Coronavirus Vaccination Do I Still Have To Wear A Mask Physical Distance

The CDC continues to monitor the spread of COVID-19 and makes recommendations for wearing face masks, both for those who are;fully vaccinated;as well as those who are not fully vaccinated.

The CDC also recommends that masks and physical distancing are required when going to the doctors office, hospitals or long-term care facilities, including all Johns Hopkins hospitals, care centers and offices.

Johns Hopkins Medicines current mask safety guidelines have not changed, and we still require all individuals to wear masks inside all of our facilities.

Vaccines Vs Delta Variant

Coronavirus Q&A: Vaccine defence against asymptomatic spread

All three vaccines are proven to be effective in varying degrees against the original variant of the coronavirus, SARS-CoV-2, that causes COVID-19.

However, since the Delta variant emerged, scientists have been trying to establish whether these vaccines are as effective against it.

We broke down what the current data says. But new research could mean this data will change over time.

Can Mrna Vaccines Change The Dna Of A Person

Since mRNA is active only in a cells cytoplasm and DNA is located in the nucleus, mRNA vaccines do not operate in the same cellular compartment that DNA is located.

Further, mRNA is quite unstable and remains in the cell cytoplasm for only a limited time mRNA never enters the nucleus where the DNA is located so it cant alter DNA.

Q: Now That The Comirnaty And Pfizer

A: Yes, it will still be necessary to continue with the public health measures that we have been following. The best way to prevent illness is to avoid being exposed to the virus. The CDC recommends the following ;preventive actions:;

  • Wash your hands often with plain soap and water. The CDC recommends washing your hands often with soap and water for at least 20 seconds, especially after you have been in a public place, or after blowing your nose, coughing, or sneezing. If soap and water are not available, the CDC recommends using an alcohol-based hand sanitizer that contains at least 60 percent alcohol. Learn more about safely using hand sanitizer.
  • Cover your mouth and nose with a cloth face covering or non-surgical mask when around others.
  • Avoid crowds and practice social distancing .

Low Vaccine Uptake Driving Up Infections

The unvaccinated population is at high risk for infection. If this variant continues to move quickly, especially in areas of low vaccination rates, the U.S. could see a surge in SARS-CoV-2 infection, said Dr. Miriam Smith, chief of infectious disease at Long Island Jewish Forest Hills Teaching Hospital in Queens, New York City.

CDC Director Dr. Rochelle Walensky issued a warning on this potential surge earlier this month.

In a press briefing, she said preliminary data suggested that 99.5 percent of the people who died from COVID-19 since January were unvaccinated.

We know that the Delta variant is currently surging in pockets of the country with low vaccination rates, she said.

In Missouri, which has a vaccination rate of nearly 43 percent, confirmed coronavirus infections surged in July.

In contrast, Vermont reported only 94 cases for the past day and currently has one of the highest vaccination rates in the country at 69 percent.

This echoes findings from a U.K. study that found the Delta variant twice as likely to lead to hospitalization, and both the AstraZeneca-Oxford and Pfizer-BioNTech COVID-19 vaccines being effective in reducing this risk.

We also know that our authorized vaccines prevent severe disease, hospitalization, and death from the Delta variant, Walensky said.

Dr. Theodore Strange, the interim chair of medicine at Staten Island University Hospital in New York, said the data supports this.

Along Come The Variants

The Vaccine Group says it is working to prevent Covid

The concern now is how much the variants might change the game, Kindrachuk says. Several of the studies from England and Israel with the Pfizer-BioNTech vaccine occurred when the B.1.1.7 variant was dominant.

The vaccines seem to be holding their own against the variants, but we also know that these variants tend to be more transmissible, Kindrachuk says. One concern is that greater transmissibility could mean it takes a lower dose to get infected, he says.

Since the vaccines dont block 100 percent of infections, its possible that vaccinated people who develop an asymptomatic infection from that variant could be more contagious than they would have been before with the strain dominant since early in the pandemic.

Further, there isnt as much data for the Moderna or Johnson & Johnson vaccines against B.1.1.7 infections, and virtually no data on infections from the other two variants of concern, B.1.351 from South Africa and P.1 from Brazil, both of which have shown some ability to evade antibodies against other variants of the COVID-19 virus.

Scientists are also studying how well the variants replicate.

If theyre replicating to higher levels, then there could be more viral shedding and more opportunity for transmission, Morrison says.

Are Young Children Susceptible To Covid

While younger children do not appear to be as easily infected with SARS-CoV-2, they can still be infected. Therefore, if a parent tests positive, they should still try to isolate from other members of the household, and all others in the home, including any children, should quarantine and be monitored for symptoms, as per CDC recommendations for exposure. The CDC has a dedicated page with guidance for situations in which a parent tests positive.

Likewise, even after parents are vaccinated, they should be aware that their children could be infected and follow public health guidance to ensure that the children are not inadvertently exposed to the virus.

Vaccine Efficacy And Effectiveness

All COVID-19 vaccines approved by WHO for emergency use listing have been through randomized clinical trials to test their quality, safety and efficacy. To be approved, vaccines are required to have a high efficacy rate of 50% or above. After approval, they continue to be monitoredfor ongoing safety and effectiveness. But what is the difference between efficacy and effectiveness?

A vaccines efficacy is measured in a controlled clinical trial and is based on how many people who got vaccinated developed the outcome of interest compared with how many people who got the placebo developed the same outcome. Once the study is complete, the numbers of sick people in each group are compared, in order to calculate the relative risk of getting sick depending on whether or not the subjects received the vaccine. From this we get the efficacy a measure of how much the vaccine lowered the risk of getting sick. If a vaccine has high efficacy, a lot fewer people in the group who received the vaccine got sick than the people in the group who received the placebo.

I Have A Weakened Immune System Do I Need A Third Dose Of The Covid

In August 2021, the FDA authorized a third dose of an mRNA vaccine for certain people who are immunocompromised. The third dose should be given at least 28 days after the second dose.

The COVID-19 vaccines, like other vaccines, work by stimulating a persons immune system to produce antibodies against the virus. If the antibodies later encounter the actual virus, they are ready to recognize and destroy it.

A person with a weakened immune system may not be able to produce a strong enough immune response to the standard, two-dose COVID mRNA vaccine regimen. This leaves them more likely to have a breakthrough infection, and increases the risk of more severe disease if they do become infected. A third vaccine dose may enhance the immune response in some people who are immunocompromised.

The FDA authorized a third dose for people who are moderately to severely immunocompromised. A person may have a weakened immune system for a variety of reasons. These include being born with an immunodeficiency, having advanced or untreated HIV, and having a chronic medical condition such as chronic kidney disease or lack of a spleen. Many types of medication also suppress the immune response, including some cancer treatments, TNF blockers, some biologic agents, and high-dose corticosteroids. Talk to your doctor if you think you may qualify for a third COVID vaccine dose.

This is a question researchers are eager to answer. People who are infected with the coronavirus show a decline in protection within a few months, but their immunity may last significantly longer than that. . Data from the vaccine trials indicate strong immunity at least months after vaccination, indicating possible long-term immunity.

As the SARS-CoV-2 coronavirus has begun to change , studies are exploring how these changes affect the viruss characteristics, including its ability to spread between people. A substantial mutation might have an impact on the effectiveness of the vaccines, and vaccine manufacturers are preparing to make adjustments where necessary.

Leaders Call For Urgency

The Ontario Liberal Party, Ontario Green Party, and Ontario NDP held a joint summit;on Monday where they discussed;the need for a provincewide vaccine certificate. They were joined by leaders across the health-care, education, business, and municipal sectors to discuss a plan for the passport’s potential;rollout, guidelines and enforcement.

After the summit, at a joint news;conference, Ontario Liberal Leader Steven Del Duca;said the vaccine certificates could ensure any disruption caused by the fourth wave is as “minimal as possible.”

Ontario Green Leader Mike Schreiner said the vaccine certificate plan must be done in a way that “creates social cohesion, supports health care, education, small business, and that’s easy for them to implement.”

Ontario NDP;health critic France Gélinas said it must be consistent, province-wide;and easy to use.

In response to questions from reporters;about the potential divisiveness of;vaccine certificates, Schreiner said the passports would only;be temporary, so people could recognize “it isn’t something that will happen for a long time.”

Toronto Mayor John Tory echoed the need for vaccine passports during a news conference on Monday with the city’s Medical Officer of Health Dr. Eileen de Villa.

Tory said the vaccine passport “has to be straightforward to get and consistent with requirements we’ve heard from employers and venue operators.”

What Do We Know About Johnson & Johnson’s Adenovirus Vaccine

Vietnam needs to change COVID

On February 27, 2021, the FDA granted emergency use authorization for Johnson & Johnson’s single-shot adenovirus vaccine, following the recommendation from the FDA’s Vaccines and Related Biological Products Advisory Committee . The vaccine is authorized for use in people 18 years and older.

In April 2021, the FDA and CDC jointly recommended pausing use of the Johnson & Johnson COVID-19 vaccine until the agencies could investigate the cases of an extremely rare but serious type of blood clot that were reported in six women who received the Johnson & Johnson vaccine. After examining the data and determining that the vaccines known and potential benefits outweigh its known and potential risks, the FDA and CDC recommended lifting the pause, and allowing use of the vaccine to resume.

The Johnson & Johnson vaccine was once again made available for use in the US, for anyone ages 18 and older. However, the vaccines label and factsheet will now warn of the rare risk of developing blood clots involving blood vessels in the brain, abdomen, and legs, along with low levels of blood platelets. The label and factsheet also list symptoms of TTS and urge anyone who experiences them after receiving the Johnson & Johnson vaccine to seek immediate medical attention.
